If you're looking for a secret weapon to take down to the bike parks then the Switchback from Stanton bikes is definitely worth a look, finished in either the gorgeous Forest Green, industrial Raw and bright Cherry Red colours for a striking head-turning hardtail.

A double butted Reynolds 631 main tube set and Head tube cupeled with Reynolds 525 seat and chain stays makes for a tough forgiving frame that shares similarities with the podium challenging Slackline.

The Tube-set is not the only thing the Switchback shares with the Slackline, it also has a strong geometric influence. the Cockpit, bottom bracket hEight and chainstay length are all taken from the Slackline and adapted to suit the 650B (27.5) wheel size. Retaining the snap, acceleration and berm hugging cornering people have come to know and love from Stanton bikes frames.

Please note that these frames are designed to show corrosion, especially in the Raw colourway, the design embraces the aging of the frame and is meant to be part of the overall look and feel. Over time the crown on the top tube will turn a rust orange while the gusset stays blue and thin rust lines with spider around the crown.
